To all whom it ma concer'nfi Be it known t at 1, Jones Hnn'rnnnnncan, acitizen of Austria-Hungary, residing at Indianapolis, in the county ofMarion and State of Indiana, have invented a new and usefulInternal-Combustion.Engine, of which the following is a specification.

It is the object of my invention .to improve the construction ofinternal combustion engines of the sliding valve type and particularlyof the sleeve type. V By my invention a valve or valve sleeve is given.an absolutely smooth motion having both axial and rotary components andis operated by a sin le train of mechanism from the crank sha t. Any)oint on the sleeve moves in a smooth closed curve. The various novelfeatures of my invention will-appear from the description and drawingsand will be pointed. out in the claims. Y V In the drawings, Figure 1 isa longitudinal section, substantially on line 1-1 of Fi 2 through a sinle sleeve gas engine form of my invention; Fig. 2 is a section throughthe sleeve, substantially on Fig. 3 is a view similar to Fig. 2 butshowing the application of my invention to a double sleeve engine.

In the preferred form of my invention, the piston moves longitudinallyin the sleeve or inner cylinder 11, and said sleeve is mounted in andmovable bothaxially and rotatively relatively to an outer cylinder orframe 12. This location of the sleeve 11, however, is not essential..The outer cylin der 12,v which may be 'acketed to provide 5 aces. 13for the circulation of a cooling uid, is fixed to thetop of a crank case14 in which is mounted a crank shaft. 15' connected tothe' piston 10 bya pitma-n 16. A counter shaft 17 is also mounted in the crank case14.near the top thereof and to one side, and, in the four-cycle engineshown, this counter shaft 17 is connecte to the crank shaft 15 by atwo-toone reduction gearing 18, 19. curve movement of the sleeve 11 isobtained from this counter shaft 17. This movement may be'obtained by anarm 20 which is located between two flanges 21 and 22 on the ever end.Qfth sleev .11 and ..i v ally connected at one 'end'to saidfianges y a23 parallel to the axis of the sleeve 11. he

line 22 of Fig. 1; and

The desired closed other end of the arm 20 is mounted on an eccentricdevice, such as a crank or eccen-- true 24, on the. counter shaft 17,the mountmg being such that a sli ht side play of the arm 20 ispermitted. T 1e sleeve 11 is provlded with one or more inlet ports 25and one or more exhaust orts 26, which cooperate, respectively, withinlet and exhaust openings 27 and 28 in the outer cylinder 12;

In the-operation of the engine, the counter shaft 17 makes onerevolution for each two revolutions of the crank shaft 15. B therotation of the counter shaft 17 an the connection between it and thesleeve 11, the latter is moved both axially and circumferentially, anyparticular point on the sleeve describing a closed curve. Because of thelong'bearing of the arm 20 on the flanges 21 and 22, the sleeve 11 ismoved vertically or axially a distance equal to the vertical componentof the movement caused by theeccentric 24, the arm 20 being maintainedalways longitudinal. This vertical component always associated with anequal horizontal component, which moves the pin 23 the same distanceabout the axis of the sleeve as a located relatively to'each other andto the inlet and exhaust openings 27 and 28 that the exhaust port isopened, or made to register with the exhaust opening 28, at'every secondup-stroke of the piston, and the inlet ports 25 are opened, or made toregister with the inlet openings 27, on the down strokes of the pistonwhich immediately follow the aforesaid up-strokes, the ports beingclosed during the remaining up and down strokes, or duringcompres'sionand explosion. It is not essential, and indeed it isusuallynot desirable, that the inlet and exhaust ports 0 en and close preciselyat the beginning and end of the intake and exhaust strokes; this may bevaried in accordance with conditions.

The same general arrangement may be applied in double sleeve engines, asshown in Fig. 3. Here there are two coaxial sleeves 11 and 11", havincooperatin inlet ports 2'' and 25 and cooperating out et ports 26Patented Ma 17, 1914.

opposite directions, from'eccentric devices 24 and 24 on counter shaftl7 in the same manner as is the single sleeve 11in the-.inoditicationshown in Figs. 1 and 2.

My invention is capable. of considerable modification from the preferredembodiment illustrated, and I aim to cover all'modifi'cations which donot involve a departure from the spirit and'scope of my invention as setforth in the following claims.

What I claim as new is:

1. In an internal combustion engine the combinationof a cylinder, acasing sleeve movable both axially and rotatively vand provided withports controlled by such movement, a piston movable in said cylinder, acrank shaft operated by said piston, a counter'shaft connected to saidcrank shaft so as to operate at one-half the speed thereof, an eccentricdevice on said counter shaft, a connecting rod transverse to thecounter-shaft and operated by said eccentric device and pivoted to saidsleeve, and means for maintaining the connecting rod parallel to aplanetransverse' to the plane in which the eccentric device moves.

'2; In an internal combustion engine, the combination of a cylindermovable both axially and rotatively and provided, with ports which arecontrolled by such movement, a piston movable in said cylinder,'a crankshaft to which'said piston is connected, a counter shaft geared to saidcrank shaft by a two-to-one reduction gearing, an eccentric device onsaid counter sh'aft,-and a connecting rod transverse to the countershaftand "operated by said eccentric device and pivoted to. said cylinder onan axis substantially at right angles to said counter shaft. y 3. In aninternal "combustion engine, the

combination of a cylinder movable both axially and rotatively andprovided with ports which are controlled by such movement, apistonmovable in said cylinder, a crank shaft to which said piston isconnected, a counter shaft geared to said crank shaft, an eccentric.device on said counter shaft, and a connecting rod transverse to thecountershaft and operated by said eccentric device and' pivoted to saidcylinder on an axis substantially at right angles to said countervshaft. 1 I

4; In an internal combustion engine, the combination with the piston, ofan eccentric device operated from the piston, a, sliding valve, and aconnecting rod between a mov-' able part of the valve and the eccentricdevice for moving the formerin a closed curved path always in the samedirection, said connecting rod being transverse to the 1,ooo,14,7

axis on which the eccentric device turns and at all -t-imes-be ngparallel to agiven plane.

5,. In an internal. combustion engine, the

combination with the piston, of aneccentric device operated from thepiston, a sliding valve, and a connecting rod of constant length betweena movable part of the valve 1 and the eccentric device for moving theformer in a closed curved path, said connecting rod always beingparallel to a given plane. i

6. In an internal combustion engine, the combination with the cylinderand piston, of a valve sleeve for said engine, an eccentric deviceoperated from said iston, apairof parallel plane flanges on saici valvesleeve,

and a connecting rod fitting between said always parallel to a givenplane.

8. In an internal combustion engine, the

combination with the cylinder vand'piston, of a valve sleeve for saideng1ne,-' an eccentric device operated fromsaid piston, and 'connectlngmeans between sald eccentric de- .vice and said valve sleeve formovingthe latter in a curved path having components both axially andcircumferentially of the sleeve, said connecting means being'rigid andatall times parallel to a given plane.

9. In an internal combustion engine, the combination with thecylinderan'd piston, of a valve sleeve for said engine, a countershaftoperated from said iston, the axis of said countershaft and t e axis ofsaid sleeve being non-intersecting, an eccentric device mountedon'said"countershaft, and a connecting rod pivoted to said valve sleeveand having a universal mounting on said eccentric device, saidconnecting rod extending transversely to thecountershaft.
